Basic contents:

Vector map of two thematic layers. Area of species distribution is shown by polygons. Zones of recorded mass reproduction and outbreak are shown by polygons.

Accuracy of classifier:

Within the species distribution area, the zone with the niduses of the Moroccan Locust mass reproduction is separated. The border of the zone of strong harm (not shown) varies, depending on pest migrations, population density, extent of area cultivated and weather conditions, spreading as far as 250 km from niduses of the mass reproduction.

Method of map production:

Scientists were given maps with boundaries of Oblasts and arable lands. After reviewing historic literature, species distribution was hand drawn on maps. If data were on the Oblast-level, distribution is on the Oblast level. In some cases, Oblast.s are further refined by boundaries of the Arable Land Map (Koroljeva et al., 2003). Hand drawn maps were scanned, georeferenced and vectorized. The map of Tsyplenkov (1970) was used as a base map and was adjusted according to the following sources: Polyakov (1975) and Lachininskii et al. (2002)-concerning Almaty Province at the Kazakhstan-China border, Kherson Region and Kuban river valley.
